Doug, I THINK it boils down to revenue.  Wire label costs are based on length 
of wire on the spool, reel, etc.  The inspector wants to make sure that spool 
did not slip out of the wire mill before the mill purchased the label.  The 
surface marking in the wire insulation does not have that level of control.

  Subject: Wire spool labeling requirements



  Over the years, there is a question that has plagued me (there are many
  others).  This one is just a curiosity and maybe someone in this group knows
  the answer.

  Four times a year we are audited for our NRTL certifications and the
  inspector makes it clear that using wire in our products with the UL
  recognition and CSA certification marks is not sufficient.  Even though we
  have incoming inspection records, it seems they always want to see the wire
  spool in our stock rooms and make sure it has the proper labels.

  I understand all the concerns with using an approved respooling house to
  maintain the integrity of the wire.  What I don't understand is how a simple
  adhesive label on the spool is better evidence than the embossed markings
  that appear along the entire length of the wire.  It seems to me that if
  someone wished to fraudulently mark a wire as approved material, the
  labeling of the spool is easily done and would be the least of their
  worries.


  Can anyone explain the history behind this requirement?


  thanks,
